The equivalent of a billion meals were thrown away unnecessarily every day around the world in 2022, according to UN estimates. Households accounted for 60% of this food waste, or 631 million tonnes worldwide in 2022 out of more than a billion in total.
The cause is the habit of buying more than necessary, misjudging portion sizes and not eating leftovers. Consumers also throw away products that are perfectly edible but whose expiration date has passed. This waste, which concerns almost a fifth of the food available, is synonymous with “environmental failure”
